The Boeing 727-231 was on final approach with the landing gear down and locked and the flaps at 15 degrees. When the flaps were extended to 30 degrees, the airplane started to roll right. Controllability was assessed and found to be satisfactory for continuation of the approach and landing. Postlanding examination of the airplane revealed the inboard section of the fore flap on the right wing had separated from the airplane. The separated flap section was located in a street of Howard Beach, NY about 2.5 miles from the approach end of runway 13L. Metallurgical examination of the respective attachment fitting revealed a fatigue crack that had originated from grinding marks on the fitting. The source of the grinding marks, (original manufacturer or rebuilder) was not determined. During maintenance, the fitting is inspected visually during a 'C' check (at 1690 hour intervals), which had last occurred 1030 hours before the occurrence.
Probable Cause: fatigue failure of the fore flap attachment fitting, due to grinding marks on the fitting.
